A:AnswerI would think they would work...to be on the safe side I would call Denon customer service (201)762-6665 and ask them. Also, Denon has their Manual online... USA.denon.com you could search for information there too.
A:AnswerA passive subwoofer needs an external power source. This receiver only has the signal output (RCA), not power for the speaker.
A subwoofer (sub) is a speaker, that is dedicated to the reproduction of low-pitched audio frequencies most commonly referred to as bass.
Passive Sub:
Passive subs are called passive because they need to be powered by an external amplifier or Audio/Video (A/V) receiver . This is similar to traditional speakers. The important thing to remember about a passive sub is that since the sub needs more power to reproduce low frequency sounds, the amplifier or A/V receiver needs to be able to send enough power to sustain bass effects reproduced by the sub without draining the power supply in the A/V receiver or amplifier.
Active or Powered Sub:
This type of sub is a self-contained speaker and amplifier. The speaker and amplifier are matched to for optimal performance and both are housed in the same enclosure. This takes a lot of the power load away from the A/V receiver and allows the receiver or amplifiers to just power the mid-range and tweeter speakers.
A:AnswerI believe the Bluetooth is only an input channel. You'd need several bluetooth output channels built into a receiver. Blue tooth speakers codec isn't good enough for Hi-Fi so why even bother?
A:AnswerYES, you can adjust the volume level for EACH channel... even TWICE if you dig deep in the settings. Or a third time when increasing the device INPUT level !
A:AnswerNO. See List of Denon AVRs supporting Bluetooth headphones transmission: https://support.denon.com/app/answers/detail/a_id/7007/~/how-to-setup-your-denon-avr-to-output-audio-to-bluetooth-headphones
A:AnswerNo, since the connection is by definition stereo it will not allow you to process it as surround sound (Dolby or DTS). However there is a multichannel stereo option which will produce sound from all speakers attached.
A:AnswerThere are two output RCA-type connections from the receiver that can be connect to 1 or 2 sub-woofers that are amplified. I have it connected two two powered sub woofers and it sounds great.
